Ever wondered what the biggest chimpanzee ever recorded looked like? You might be surprised. Meet Boma, a male chimpanzee who stood over 5 feet tall and tipped the scales at a wild 236 pounds. That’s way bigger than your average chimp, honestly—Boma’s just in a league of his own.
Most chimps weigh about 130 pounds and stand somewhere between 3 to 4 feet tall. Boma’s size really jumps out at you.
His muscular build and unusual height came from a mix of genetics and the way he was raised. Learning about Boma just might change how you see chimpanzees.
Besides their size, chimpanzees fascinate us with their intelligence and social lives. There’s more to Boma than just his weight and height—his behavior and strengths reveal a lot about these big apes.
Largest Chimpanzee Ever Recorded
Chimpanzees can vary a lot in size. Some individuals end up much bigger than you’d expect, thanks to unique genetics or the way they grew up.
Let’s look at what’s confirmed, meet some famous big chimps, and sort out what’s real from what’s just myth.
Confirmed Size Records
Boma takes the crown as the largest confirmed chimpanzee. He weighed 236 pounds and stood over 5 feet tall.
That’s a huge jump from your average male chimp, who weighs about 130 pounds and stands 3 to 4 feet tall.
Here’s a quick size comparison:
| Trait | Average Male Chimpanzee | Boma (Largest Recorded) |
|---|---|---|
| Weight | 130 pounds | 236 pounds |
| Height (standing) | 3 to 4 feet | Over 5 feet |
Boma’s upbringing and diet helped him get so big. He grew up in the wild but also got food from humans, which definitely played a part.
Some people talk about wild chimpanzees like the Bili apes being just as large, but no one has confirmed those sizes for sure yet.
Famous Individuals: Boma and Others
Boma’s the star when it comes to giant chimps. His broad face, big jaw, and strong body made him impossible to miss.
His fingers and toes were longer than most chimpanzees, which let him grip things really well.
People also talk about the Bili apes from the Congo, sometimes calling them lion killers. These apes are supposed to be huge and walk upright, almost like people. But scientists still debate whether they’re a different species or just unusually big chimps.
Other big chimps have been spotted, but none match Boma’s confirmed size. These individuals show just how much chimps can vary, depending on their genes and where they live.
What Makes Some Chimpanzees Larger?
Several things can make a chimpanzee bigger than normal. Genetics matter—a lot. Some chimps just inherit the right mix for size and muscle.
Diet and care play a big part too. Boma ate fruits, veggies, and even meat, which helped him bulk up.
Chimps in captivity or with access to more food often grow larger than those in the wild.
Where a chimp lives also makes a difference. Chimps in lush forests with lots of food usually grow bigger than those in tough environments.
But being too big can make it hard for a chimp to find enough food or even a mate in the wild.
Myths vs. Scientific Evidence
People love to exaggerate stories about giant chimps. Some say chimps get as tall as humans, or even bigger, but that’s almost never true.
The Bili apes, for example, are surrounded by wild tales. Some folks claim they hunt lions or are a whole new species, but scientists haven’t found proof they’re much larger than regular chimps.
It’s best to stick to actual measurements and confirmed sightings. Boma’s size is real and verified.
Most other stories about giant chimpanzees come from legends or unproven reports.

Bili Apes and Giant Chimpanzee Legends
You might not expect a group of chimps known for their size and strange habits, but the Bili apes really stand out. They live deep in the Democratic Republic of Congo, and people have debated and studied them for years.
Their behavior and looks set them apart from other chimps.
Discovery and Research on Bili Apes
People first noticed the Bili apes over a hundred years ago when someone collected odd skulls near the village of Bili in northern Congo.
For ages, nobody really knew what these apes were. In the 1990s, researchers like Karl Ammann started looking for them again.
Scientists from places like the Jane Goodall Institute and the Max Planck Institute joined the search in the early 2000s. They used cameras and DNA tests to figure out what made these apes different.
Eventually, they confirmed that the Bili apes are actually a subgroup of eastern chimpanzees, even though they look pretty unique.
Distinct Physical and Behavioral Features
Bili apes tend to be bigger than regular chimps. Some adults stand over 5 feet tall, which is almost gorilla height.
Their skulls and footprints are often larger than those of gorillas, which is pretty wild.
Unlike most chimps that build small nests in trees, Bili apes make big nests on the ground.
Locals call them “lion-killers” because they’re strong and seem fearless, not backing down from big predators.
Stories about them howling at the moon or hunting lions pop up a lot, but those are mostly exaggerated. Still, their size and ground-living habits make them stand out.
Debate: Species, Subspecies, or Local Population?
People argued for a long time about whether Bili apes were a new species or maybe even a mix between chimps and gorillas.
Their gorilla-like jaws and chimp-like faces made it confusing.
DNA tests eventually showed that Bili apes belong to the eastern chimpanzee subspecies (Pan troglodytes schweinfurthii).
Their weird traits probably come from living so isolated for so long, not from being a new species.
Turns out, when animal groups get isolated, they can pick up some surprising features but still belong to the same subspecies.
Conservation Challenges and Habitat Loss
Bili apes face some tough challenges these days. The forests they call home keep shrinking because of logging, hunting, and farming.
People have pushed their small populations into even more isolated pockets. It’s honestly a worrying trend.
Protecting their environment isn’t easy. These apes live out in remote wetland and savannah regions, which makes everything more complicated.
Local communities try to help, and some conservation groups have joined in to spread awareness. They’re all searching for ways to keep Bili apes safe, but there aren’t any simple answers.
If you follow news about chimpanzees, you’ve probably noticed the concern over Bili apes. Their survival really does hinge on what happens in the Democratic Republic of Congo.
